In a central air conditioner, the air coil absorbs heat from household air that is passed over it by the air handler. This cools the air in your home, while also removing humidity. In certain conditions, the absorption of heat can be reduced, allowing the air coil to cool and ice to form from the moisture that is removed from the air. Once the coil freezes, your air conditioner will not be able to cool properly, and it may stop working completely to protect the compressor from damage.
There are several conditions that can cause the air coil to freeze, including:
If your air coil freezes, you should shut the air conditioning system off by raising the temperature on the thermostat. Allow the air coil to thaw naturally, and do not use any tools, like scrapers, to remove the ice, as they could puncture the coils. Clean or replace your air filter if it is excessively dirty or clogged, and check all the vents in your home to make sure they are not closed or blocked by furniture, drapes, or other objects.
Restart the system once the coil has thawed completely, and if it freezes again, it is a good idea to have the system professionally inspected.
